WRINGER ATTACHMENT.

Appiication filed Catcher 2, 1924. sensi No. 741,142.

rilhis invention relates to a wringer attach ment for clothes, washing machines, wash tubs. trays, and the like.

The object of the present invention is to provide a clothes wringer driving and supporting mechanism which may be attached to an ordinary wash tray having two or more compartments formed therein; to provide a clothes wi'inger driving and supporting mechanism which is adapted to cooperate with an ordinary domestic type of power driven washing machine, and also adapted to be driven thereby; tov provide a clothes wringer driving and supporting mechanism which permits movement of the clothes wringer from one compartment of a wash tray to another; and further, to provide a gear transmission whereby power may he transniitted to theawringei' i'ollshoth aheac and reverse, and whereby a neutral position may be assumed.

One form which my invention may assume is exemplified in the following description and illustrated in the'accoinpanying drawings, in which- Fig. 1 is a perspective view showing the application of the invention. i

VFig. 6 isa plan view of the transmission case.

Referring to the drawings in detail, and particularly to Fig. 1, A. indicates in general a domestictype of clothes washing machine. B a standard form of lcement wash tray, and C a standard form of clothes wringer.

rlphe invention forming the subject matter of the present invention is a clothes wringer supporting and driving mechanism which is generallyT indicated at D. This mechanism consists of a pair of end frames or standards 2 suitably secured to a base plate or board 3. Formed in each standard 9. is a bearing member land extending through the bearing members and journalled therein is a main driving shaft 5. This shaft has a key-way or spline formed therein, as indicated at 6, and this entends from end to end of the shaft for purposes hereinafter to be described. The shaft 5 is adapted to be d riven from either end and it is particularly intended that it should be driven in unison with a washing machine such as indicated at A. This machine is driven by means of an electric motor E, said motor transmitting power to a vertical shaft 7 which in turn transmits power to the impeller or other agitating device disposed within the washing machine. Power is in this instance transmitted from the vertical shaft 7 to a bevel gear 8. This isrjoui'nalled in a bearing 9 formed in lan extended portion 10 of an enclosing housing such asshown in Figs. 1 and 5. The gear shaft ll carrying the bevel gear 8 is recessed or hollow in one end and a bayonet 4slot is formed in the shaft as indicated at 12,

the recessed end being provided for the reception of an intermediate lshaft 13, and the bayonet slot for the reception of a pin 14 carried thereby. The bayonet slot land pin form a driving connection between the shafts l1 and 13 and shaft 13 in turn serves the functionof driving the shaft 5, this being accomplished by recessing the ends of the shaft 5, as indicated at 15', and securing the shaft 13 therein, for instance, by means of a setsciew 16. The connections 14 and 16 serve the function of universal joints and thus eliminate the necessity of any eXact'aligning` of the shafts when installingthe wringer attachment.

The base or board section 3 upon which the standards 2 are carried is secured to the wash tray B in a substantial and simple manner; that is, the base board is drilled or perforat- Yed adjacent each end and bolts 'such as indi- 'cated at 17 (see Fig. 2) are passed therethrough'. threaded to carry hook-shaped members 17 The-lower ends of these bolts are tion of driving the wringer C and also that of supporting one end of the same. rlhis is accomplished in the following manner: Slidably mounted on the shaft 5 is a gear transmission case 20 (see Figs. 3, et and t3), and slidably mounted on the shaft within the transmission case is a pair of bevel gears 2l and 22. These gears are splined te the shaft 5 and as such are constantly rotated in unison with the same. Extending through one side of the gear case and journalled therein is a shaft 23. A bevel gear 24 is secured on the outer end of the shaft, and gears 2l. and

are adapted to be thrown into mesh therewith and they are also adapted to assume a ral position when the wringer is not in ration. lhe shaft 23 is connected to the shalt 25 of the lower wringer roll 26 through means of a pin and slot connection such as indicated at 27, and the upper roller is merely frictionally driven thereby. The wringer frame generally indicated at C is secured to the transmission lase by means of bolts 30 and as such is supported thereby; that is, one end of the wringer is supported by the transmission case but the opposite end of the yringer is provided with a foot which rests on the outer edge of the wash tray, as indicated at 3l (see Fig. l). FEhe transmission case, to which the wringer is secured, is freely slidable on the shaft and is freely turnable thereon, and the outer end of the wringer may thus be grasped and lifted upwardly and then pushed from one end to another of the main shaft 5, when it is desired to shift its position from one vy'ash tray compartment to another; or the foot 3l may slide along` the outer eee-e of the wash tray when changing the position of the wringer.

Means are provided for shifting the gears 2l and 22 into or out of mesh with relation to the gear 52e, and also to maintain the gears 2l and QQ-in neutral position with relation thereto. rhe means employed is a cover member 35, This cover is slidably mounted on the transmission case 20, and it is provided with a pair of downwardly extending` lugs 36 one at each end. These lugs engage the ends of the gears 2l and 22 and any movement imparted to the cover member 35 will thus simultaneously be imparted to the gears V2l and 22. To move the cover a shifting lever 37 has been employed. i pin 38 carried by this lever engages a forked eX- tension 39 of the cover and movement imparted by means of the lever 37 is thus transmitted to the cover. The lever is also provided with a segrental extension such as indicated at 40. rlhis extension has three recesses formed therein as indicated at 4l. These recesses are alternatively engaged by a spring-actuated pin e2. This pin serves the function of frictionally securing the lever 3T against movement; that is, the tension of the spring on the pin 42 is suiiicient to secure the lever in any one of three positions desired, to-wit, neutral, ahead or reverse. The central depression il maintains the gears 2l and 22 in neutral position, while the end depressions or recesses 4:1 maintain the gears in mesh with the 2a either for ahead or reverse movement. :l neutral position is necessary as shaft 5 is continuously driven when the washing machine is in operation, and it is obvious that power should not be transmitted to the wringer except when it is required.

rllhe wringer attachment here shown was signed with the idea in view that a housewif e could do her washing without moving the washing machine and at the same time be able to wring from the washing machine into the trays or from the trays into a clothes basket. The attachment was also designed with the idea in mind of leaving a clear passage in front of the wash trays, this being accomplished by placing` the washing machine at one end instead of in front of the trays, as is usually the case. By placing the washing machine at one end or another of the wash trays, it is possible to permanently connect it with a sewer and also to install permanent water faucets. rEhe main shaft of the wringer attachment is so designed that it may be driven from either end. This permits the washing machine to be placed at either end of the wash trays and permits it to be used in a narrow wash-room. The device as a whole is exceedingly simple and substantial, and it is easy to operate and as such has proved a4 great convenience as far the average household is concerned.

lWhile certain features of the present invention are more or less specifically illustrated, wish it understood that various changes in form and proportion may be resorted to within the scope of the appended claims. I similarly wish it understood that the materials and finish of the several parts employed may be such as the experience and judgment of the manufacturer may dictate or various uses may demand.

Having thus described my invention, what I claim and desire to secure by Letters Patent isl. A clothes wringer and driving and supporting mechanism therefor comprising a frame, a main shaft extending from end to end of the frame and journalled therein, a gear transmission case slidably mounted on said shaft, a clothes wringer secured to said gear transmission case, said transmission case and clothes wringer being movable from end to end of the shaft, wringing rollers in the wringer, a pair of interspaced bevel gears splined on the main shaft and disposed within the transmission case, a bevel secured to a shaft carrying one of the vringer rolls, said bevel gears being also disposed within the transmission case, a sliding Cover on the transmission oase, lugs on said eover engaging the pair of bevel gears, and means for transmitting movement to the cover and the gears to shift the same either to a neutral position With relation to the single bevel gear, or to a position Where one or another of the pair ot bevel gears Will interniesh therewith.
